To all whom firmly concern."

Be it known that LKVILLIAM H. QLXUNKST, a citizen of the United States, residing at Milton, in the county of Northumberland and State of Pennsylvania, have invented a new and useful Pneumatic Pump, of which the following is a specification.

The present invent-ion appertains to pneumatic pumps or water elevators, and aims to provide a novel and improved apparatus of this character. p p y One of the objects of the present invention is to provide an apparatus of thecharacter indicated which may be lowered intoan Arteslan well, a .nnne'shaft, or the like,

in order that water or "other liquids therein may be elevated or hoisted by pneumatic pressure in an efficient and novel manner.

Another object of the present invention is to provide a device of the nature indicatedwhich shall embody a pair of superimposed compartments into which the water may flow alternately, the pump being operable by pneumatic pressure in order that the water may be elevated alternately from the respective compartments to the surface or to any desired point.

A still further object of the presentinvention is to provide a novel means for permitting the air to escape from the respective compartments, after the water has been forced therefronnin order that fresh water may flow thereinto, so that a continuous or non-intermittent action of the pump may ensue;

Another obj ectof the present invention is to provide a pumpof the character indicated which shall be of relatively small cross sectional area so as-to enter an 'Artesian well or circumscribed passage without detracting from the utility of the device, the

' device being capable of being constructed of the invention.

of various lengths according to the depth of the well or the like. I

With the foregoing general ob ects outlined, and with other objectsin View, which will be apparent as the nature of the invention is better understood, the present invention resides in the combination and arrange ment of parts and in the details of construe tion hereinafter described and claimed, it being undertsood that'chan'gesin the precise embodiment of the invention herein disclosed can be made within the scope of what isclaimed Without departing from the spirit vice.-

' compartment 6.

The invention has been illustrated in its preferred embodiment in the accompanying draw ng, wherein similar reference char' acters have been employed to denote corresponding. parts, and wherein:

Figure 1 is a longitudinal central section of the apparatus, parts being broken away. Fig. 2 is a top or upper end view of the de- Fig. is. a fragmental detail in section; Fig. 4- is a sectional detail of the valve structure for one of the compartments,

which is operable to permit the air under pressure'to enter the compartment, so as to force the water therefrom, and to then perm mit'the air to be discharged from the coni-' partment after the water has been forced therefrom. details'illustrated in'Fig. 4. I

In carrying out the invention, reference being had to the accompanying drawing, there are provided a pair of superimposed compartments or chambers Band 6, each of which maybe of any desired length and cross sect1on. the upper compartment 1S spaced Sufiiciently above the upper end or top of the compartment 6 and is provided-withone or The lower end or bottom of Fig. 5 is a cross section of the,

more inlets 7 closed-normally by outwardly between the adjoining ends of the compartby outwardly seating. check ments so as to permit of the influx of water,

I andin order to exclude the ingress offoreign or extraneous matter, and 'a similar cage or guard'9 is secured to the lower end of the compartment 6;-

An air chamber or compartment 10 "is mounted on the upper end of the compare ment- 6, the same being preferably in the form of a hood secured at its edges to the vided with 'aninlet 11 to which is attached "the supply-or feed pipe for the compressed air or fluid. The. supply of compressed air may" come from any suitable source, as

"will be evident. I

The eduction or discharge pipeor conduit for the water has been designated b'ythe of thecompartments 6 and-6 along one side,

thereof, and extending upwardly through] the chamber 10110 the atmosphereor to any 1 The chamber 10 s pronumeral 12,"the" same extending 'i'nteriorly desired point where the water is to be discharged. The conduit 12 terminates at its lower end adjoining the lower end of the compartment 6, and is provided adjoining the respective lower ends of the compartments 6 and 6, with the inlets 13 and 13 normally closed by the outwardly seating check valves 14 and 14.

i The upper end of the compartment 6 is provided witha pair of sleeves 15 and 15, which provide passages through the upper end of the compartment 6, and which are provided at their upper ends with the valve between the arm 19 and the plunger 20 may swing to either side of the axis of the device as the respective valves are seated. A coiled wire spring 22 is mounted on the plunger 20 and seats between the lowerend'ofthe plunger and the support 21, so as to yieldingly hold the arm 19 to one side or the other. Thus, it will be noted that the arm' 19 and the plunger 20, when swung into alinement, will compress the spring 22, and when the lever 13 is swung in one direction or the other, the spring 22 will serve to seat the respective valves 17 or 17. i a

The respective valves 17 and 17 areprovided. with. the depending spiders 23 and 23 slidable in the respective'sleeves 15" and 15, and to the respective spiders there are attached the depending actuating rods 24- and 24. The lower end of the rod or link 24 is pivoted to a lever 25 fulcrumed within the compartment 6, while the rod or link 24 extends through the lower'end of the compartment 6 and into the compartment 6, and is pivoted to a lever 25 fulcrumed within the compartment 6. a The respective levers 25 and 25 have the links 26 and 26 hung therefrom, and to the lower ends of the respective links 26 and 26 are attached the floats or buoyant members 27 and 27.

A pipe or tubular member 28 is passed through the lower end of the compartment 6 and is attached at its lower end to the upper end of the compartment 6,and at its 1 upper end is attached to the lower end of the sleeve 15, so that the rod or link 2 1- may pass through the adjoining ends of the compartments 6 and 6 without the necessity of stufling boxes orthe like. It will thus be.

noted that'the pipe 28 and the sleeve 15" provide a passage form the air chamber 10 into the lower compartment 6, while the sleeve 15 provides a passage from the air chamber into the upper compartment.

The eduction or discharge pipe for the air has been designated by the numeral 29, the same passing through the hood or air compartment 10 and having a pair of branches 30 leading to the respective sleeves 15 and 15. They branches pass through the respective sleeves and have their extremities do \vnturned or depending, as denoted by the numeral 31, Fig. 4;. The extremities of the branches 30 are formed into valve seats which face downwardly. v

A valve 33 is carried within each of the spiders 23 and23, and has a depending stem 34 passing slid-ably through the center or hub of the spider. The stem 34 is provided with a nut or stop 35 on its lower end adapted to normally seat against the spider. so as to limit the upward movement of the valve and a coiled wire compression spring 36 is mounted on the stem 34 between the valve 33 and the spider so as to yieldingly support the valve 33. Each of the respective valves is adapted to seat upwardly against the seat 32 when the respective valve 17 and 17 is raised, and when the respective valve 17 or 17 is seated, the corresponding valve 33 is lowered or unseated.

In the operation o-f-the device, it being understood that the compartments 6 and 6 have been lowered into an Artesian well, mine shaft or the. like, so that the water or other liquid may flow into the respective cages 9 and 9, the water may flow into the respective compartments 6 and 6 through the check-valved inlets. Taking the parts as depicted in Fig. 1, the compressed air or fluid is adapted to pass from the air chamber 10 down through the sleeve 15 and pipe 28 into the compartment 6, so that ment 6" will be forced upwardly through the inlet 13 into and up the eduction conduit 12 to the surface or atmosphere. It

any water accumulated within the compartwill be noted that when the air flows or is forced into the compartment 6, the check valvesS will be seated so as to prevent the water from being discharged through the inlets 7. It will be noted that when the valve 17 is raised, the float or buoyant member 27 will be raised, and the respec the egress of air throughthe pipe 29, and after the water has been forcedfrom the compartment 6, the'float 27 will be lowered or will gravitate so as to tend to seatthe valve 17. In the meantime, the valve 17 will be seated, and the valve 33 complementing the valve 17 will be unseated so as to open the respective branch 30 of the discharge pipe 29' and as a consequence, the water may flow through the inlets 7 into the compartment 6, the super-incumbent air tive valve 33 will be seated so as to prevent being discharged through the pipe 29 to the atmosphere. It will also be noted that as the COIDPtLltlllQHt 6 fills withgwater, the float 27 will be raised and due to the combined or aggregate, movements-of the two floats, the lever 18- will be swung, clock-wise as seen in Figl, so asto unseat the valved? and in order to seat the valve 17,'the re spective valves 33 being seated and unseated correspondingly Th us, it"will be ,ob served thatthe floats 27 and 27 cooperate in a novel manner, the buoyant tendency of onewfloat cooperating with the gravitating tendency of the other to swing the lever 18 and its arm 19 beyond dead center so as to reverse the positions", of the valves 17 and 17. a r

After the above operation has ensued, that is, after the compartment 6 has been filled or partially filled with water, and afterthe compartment 6 has been'emptied, so'as to unseat the valve 17 and seatthe valve 17 the rev rse operation will take place, the air now being forced through the sleeve 15 1nto the compartmen'tfi so as to force the water through the inlet 13 into and up't-he eductionconduit l2,-the check valve 14: closing the inlet 13 leading to the compartment 6. In the meantime the water will flow through the inlets 7 through the pipeQS, the sleeve 15". and discharge pipe 29 to the atmosphere.

In the manner above described, it will be observedthat each of the compartments is intermittently filled with water, and then objectionable, especially in a pump of the present character.
